Parking meter communications for remote payment with updated display

ABSTRACT

A parking meter receives data indicative of a remote payment being completed and displays an amount of time purchased by the remote payment for a parking session. The parking meter determines an amount of time remaining in the parking session and powers down at least a portion of a meter communication subsystem subsequent to receiving the data indicative of the remote payment being completed. The parking meter wakes up the powered down portion of the communication subsystem upon determining that the amount of time remaining is below a threshold time, and can receive an indication of additional time being paid for remotely, and can update the displayed time remaining to reflect the additional time.

BACKGROUND

A parking meter is typically associated with a single parking space suchthat the parking space can be occupied for a predetermined amount oftime in accordance with the amount of payment received at the meter.Expiration of the amount of time at the meter exposes the vehicleoccupying the parking space to a fine. Advances in meter technology havegenerally not been propagated for managing parking meter enforcement andparking meter fee payment. Enforcement of parking meter fees is stilllargely performed by an individual manually traveling to each parkingspace and checking the time remaining on the associated parking meter.The individual is generally charged with noting violations of feepayment and issuing citations. This is a time-consuming and costlyservice. As with many tasks, manual involvement produces inefficienciesand unreliability.

For some systems, it is possible to provide payment to a parking metervia a mobile telephone, also referred to herein as a cell telephone.Such payment systems are typically referred to as pay-by-cell systems.The pay-by-cell technology has evolved in the parking industry as amethod for cashless payment, as an alternative to cash-based payment andfor when debit card, credit card, or other cashless forms of payment arenot readily accessible. This has been especially true in the singlespace parking meter market. The pay-by-cell technology involves eachparking meter unit being turned on (i.e., electrical power is applied)at the time a user initiates a paid parking period (i.e., begins aparking session). When the parking meter is turned on, it cancommunicate with the local cell telephone infrastructure to complete thepayment transaction and start the timing process.

The pay-by-cell technique provides a more convenient cashless payment,and can also have the ability to add additional time to a parking spaceremotely. For example, if a user of a pay-by-cell parking space is stuckin a meeting and knows that it will be necessary to purchase more timebefore the meeting ends, then the user can do so by the followingprocess, described in Table 1:

TABLE 1 Step Operation 1 User registers with a parking service provider,providing credit card and associated cell phone information for paymentof future parking sessions. 2 User decides to use pay-by-cell in adesignated location. 3 At the designated location, the user initiatespower to the parking meter and places a call to a central database ofthe parking service provider, while the parking meter communicates withthe central database. 4 The user provides information on parkingpole/space location and amount of time to be purchased to the centraldatabase. 5 Time is granted and details regarding the purchase arestored in the central database (service provider hosted). 6 In responseto the user payment, the central database communicates the amount oftime purchased to the meter at the designated location. 7 Some timeafter initiating the parking session, the user can decide to payadditional amounts to extend the time period for the parking session bycommunicating with the central database and authorizing payment.However, because the parking meters are not always awake (theypower-down to save power), the updated time cannot be communicated fromthe central database to the meter for display. 8 Because the meter doesnot display the time added in Step 7, enforcement requires officers tocheck with the central database for paid time, prior to issuing acitation, because a meter with a display that indicates the parkingsession has expired may actually have time remaining, due to the Step 7payment. This need for checking is cumbersome and time consuming, makingenforcement difficult.

Performing the above pay-by-cell process is time consuming to the user,requiring the user to register, place a call, and note the location andthe amount of time to be purchased. In addition, the availability ofcredit card payment for both multi-space and single-space parking metersis likely to have a negative impact on pay-by-cell use due to the easeand speed of paying with a credit card. Some feel that pay-by-cell isakin to paying with a credit card, but using a cell phone to do so.Again, this is a more time consuming and confusing process than justpaying with a credit card directly.

The above pay-by-cell process is also difficult from an enforcementperspective, as it requires enforcement personnel to contact the centraldatabase to determine if time has been added to the meter. Enforcementpersonnel would prefer to determine if a meter/space has time remainingby simply looking for an updated expiration indicator on the meteritself. The need for checking with the central database to determineremaining time, on a meter that otherwise indicates time has expired,translates into a slower enforcement pace and reduces the number ofspaces that can be monitored by enforcement officers and reduces thecitations issued for expired meters, which also translates into lessrevenue for a city or parking authority.

Some companies have implemented new technologies to address the primarydrawbacks discussed above, with limited success. For example,enforcement personnel can be provided with Web-enabled access topay-by-cell central databases. However, this still requires additionaltime and money to perform the checking. Meters can be configured tocommunicate over low-power mesh network wireless systems to enable themeters to always be awake and thereby receive updated data over the meshnetwork. This allows the meters to keep their displays updated and showthe additional purchased time. However, mesh network parking meters arenot without problems.

Mesh network parking meter systems require additional infrastructure,including wireless routers installed at various locations throughout thewireless network to act as the focal points of communication. Theserouters typically require electrical power on a 24/7 (twenty-four hoursper day, seven days per week) schedule, and therefore mesh networkparking meters are typically installed on street light, traffic signal,or other city utility street poles that can supply power to such units.In more complicated systems, additional router communication units areinstalled to provide levels of redundancy, and repeaters may also beinstalled to extend the geographic coverage of the mesh network.

The additional mesh network infrastructure requires installation andmaintenance. Installation of the wireless routers is costly, can requirepermitting, and consumes electricity. This creates any number of issues,depending on which entity owns the poles, the permitting process andadded bureaucracy to determine how to pay for the consumed electricity,allocating responsibility for who will maintain the installed routersystem, and what will be the impact if a router fails.

Mesh network technology can be relatively expensive in terms of materialcosts, maintenance costs, installation, and permitting costs. While itis possible that other services can be processed through the meshnetwork, the economics of the service is such that few customers arewilling to make such an investment of money and resources to install andmaintain mesh network parking systems for such a limited economicreturn.

Due to the cumbersome steps in current pay-by-cell processes,pay-by-cell payments typically represent less than 5% of all parkingrevenues for a given city. In areas with a younger demographic, andespecially in university settings, pay-by-cell is typically more popularand higher percentages of its use are typical. However, a morestreamlined pay-by-cell process, from the perspective of both the usersand the enforcement personnel, could result in greater acceptance andmore pay-by-cell payments.

DETAILED DESCRIPTION

According to one embodiment of a parking meter as described herein, amanagement system having a central database communicates with parkingmeters that are not continuously on, such as in a pay-by-cellconfiguration, and the parking meters themselves will initiate power onand communication with the management system just prior to expiration ofthe parking session, to determine if additional time has been purchased.If no additional time has been purchased, the parking meter will let thetime for the parking session expire as it normally would and itsassociated display will show expiration (zero time remaining). Ifadditional time has been purchased, then the management system willprovide the new expiration time to the parking meter when the parkingmeter initiates the communication. The parking meter includes a radiotransceiver for communicating with the management system. Operation ofthe parking meter includes transmitting radio signals to, and receivingradio signals from, the management system. In this way, enforcementpersonnel are always assured that the display of a parking meter iscurrent and updated to show actual remaining time. It is not necessaryfor enforcement personnel to check the central database of themanagement system before issuing a citation for an expired meter. Thus,a more streamlined pay-by-cell process is provided, and both users andenforcement personnel benefit from a more convenient process.

In the disclosed system, paying with a cell phone will not require theuser to call into a central call center. Instead, users will registerwith the management system, at which time they will provide credit cardand cell phone information. The registration may be completed via a Website. After registration, the user will receive some form of registereduser identifier for communicating to a parking meter. The useridentifier could be in the form of, for example, an identification card,an account number, a credit card, a debit card, a smart card (contact orcontactless), a contactless RFID tag or a driver's license. The useridentifier creates an association between the registered user's creditcard (or any other type of payment account), the ID of the registereduser, and the registered user's cell phone number. The user identifiermay be carried on the person, or can be placed on a key chain, in awallet, or affixed to the back of a cell phone. Other arrangements arealso acceptable. The user may provide the system with the useridentifier and the system will associate the user's registrationinformation with the user identifier.

When a user wishes to pay for a parking session, the user will initiatea payment session. In one embodiment, the user will press a button onthe parking meter to activate a RFID tag reader of the parking meter andwill present an RFID tag in close proximity to the parking meter. Inother embodiments, the user will slide a credit card or debit card intoa magnetic card reader of the parking meter. In other embodiments, asmart card (contact or contactless) reader is activated by the user toread a smart card. The parking meter reads the user identifier andcommunicates the user registration identification information to themanagement system, which can thereby associate the registered user andcredit card information in the system database. Once the user identifieris read by the parking meter, the user will use the parking meterbuttons to complete the payment transaction. If the user identifier isan RFID tag affixed to the user's cell phone, the reader may beactivated by selecting buttons on the cell phone. After the paymenttransaction is completed, the parking meter receives data from themanagement system to set the parking session time. In other embodiments,the parking meter may receive the user identifier by reading input fromthe user, for example, by user input via a keypad or the like.

Making payment using an RFID tag and the parking meter RFID reader canbe just as quick as payment with a coin or credit card. Purchased timewill be displayed on the parking meter and the credit card associatedwith the RFID tag will be processed for payment (which could be in bulkor for each transaction).

The parking meter includes a timing mechanism that counts down the timeremaining in the parking session according to the payment made. When thetime on the parking meter is about to expire, the meter or associatedmeter management system can send an expiration message to the user viathe phone number associated with the user identifier used for theinitial payment and/or via email or the like to ask the user if the userwishes to purchase additional time. If the user does not, then the meterlets the time for the parking session expire and it sets a display orother indicator accordingly. Enforcement personnel can then issue acitation, if appropriate. If the person wants to purchase additionaltime in response to the expiration message, the person can accept to payvia return email or text message or the like. The expiration message tothe user can identify the parking space location. The return responsefrom the user will contain information on the pole number (or otheridentifier of the parking space location) and the additional time to bepurchased. Since the phone number used to direct the expiration messageis associated with a credit card of the registered user, the credit cardcan be processed for additional time. The card associated with theregistered user can be a debit card or other form of payment card.Moreover, it is optional that the user's registered account may beconfigured so that the user's payment card is pre-authorized to payparking charges from the management system, or the user may establish apre-paid debit account with the management system, such that additionalcharges to extend the parking session will be automatically deductedfrom the user's account on file once the additional payment has beenprocessed and authorized.

Thus, the parking meter will automatically initiate a communicationsession with management system just prior to expiration of the parkingsession to determine if additional time has been purchased. If noadditional time has been purchased, the meter will let the time expireas it normally would. If additional time has been purchased, theninformation about the additional time for the parking session will bedownloaded directly to the parking meter during the communicationsession and the parking meter will update its display accordingly. Theparking meter will then deactivate at least a portion of itscommunication subsystem (i.e., power-down some of its circuitry) toreduce power consumption. The internal timer mechanism of the parkingmeter will continue to run, until expiration of the parking session isimminent, at which time the communication process described aboverepeats. In the system described, the additional time purchased via cellphone is displayed on the parking meter without the use of a meshnetwork for communication, and does not require any special efforts byenforcement personnel to check with the management system beforecitation at an expired parking meter.

The parking meter may be a single space parking meter. Preferably, thesingle space parking meter displays an amount of time paid for, therebynot requiring a printer to print out tickets such as commonly used inmulti-space parking meter systems.

The transceiver of the parking meter may have a maximum range of up to150 meters, but could operate at less than 80 meters. The parking metertransceivers may operate in the 2.4 GHz frequency band and may have apower of between 1 mW and 6 mW. At low power levels, batteries couldlast for months or even years (e.g., up to three years or more).

The parking meter may have a payment received arrangement for receivingan instruction from a call center that payment has been effected, viathe call center, from a cellular telephone.

The parking meter may have a solar power charging arrangement wherebythe power supply unit is recharged by solar energy. The parking meterdevice may then also have a power management facility.

As a further feature, the parking meter may have a locating arrangementfor independently determining the geographic location of the parkingmeter. The locating arrangement may be GPS-operable.

The parking meter device may have a management communication arrangementfor communicating management information to a management system. Forexample, such management information may include malfunction details, atampering alert, duration expiration and the location of the parkingmeter device.

Embodiments of the disclosure include a method of controlling parking ina single parking bay, which includes accepting payment for parking inthe bay by means of coins, parking tokens, a credit or debit cardaccount, a smart card, from an electronic purse, or by means of acellular telephone.

If payment is effected by means of a cellular telephone, then the methodmay include receiving an authorization signal that payment for theparking has been made. This signal may be provided by a second financialinstitution or from a control center.

Instead of an additional payment being received in response to theparking meter communicating a message to the data manager due to a timerreaching a threshold level, a user could initiate the payment with thedata manager by placing a call to the system and being placed incommunication with the data manager. The data manager then initiates acommunication session with the parking meter and transmits theadditional time that was purchased to the meter. The parking meter maybe in a low power mode such that an incoming call can be received andfull operation can be restored, or the parking meter may always be in afull power mode.

The method of controlling parking may include sensing a vehicleidentifier associated with the vehicle that is parking at a parkingmeter. The vehicle identifier uniquely identifies the vehicle and maycomprise any of a variety of mechanisms. For example, the vehicleidentifier may be a license plate number that is optically detected. Thevehicle identifier may be contained in an RFID tag that is attached tothe vehicle. An RFID tag on the vehicle could be activated by a parkingsensor that is located in proximity to the parking space. The parkingsensor can wirelessly communicate the vehicle identifier to the parkingmeter. The vehicle identifier may be stored at the data manager andlinked with a user identifier (e.g., an RFID tag identification number),the credit/debit card, phone information and/or email information of theregistered user.

The method of controlling parking may include sensing if a vehicle isparked in the parking space or bay when the paid-for parking time hasexpired or the maximum parking time has been exceeded, and transmittinga time expired signal to a management center. A location signal,providing the location of the parking space, may also be transmitted.

The data manager may comprise a plurality of data managers that includeone or more local data managers that in turn communicate with themanagement system.

A predetermined number of single-space parking meters, together with anassociated local data manager, can form a local group, such that thelocal data manager communicates with the management system on behalf ofthe group or any of its members.

The communication facility of a local data manager may communicate withthe management system by means of a data channel, which may use acellular telephone network, a wireless local area network (LAN), a wiredLAN, or the Internet.

Communications between the parking meters and the management system maybe in regard to payment authorization, arrival event reporting, paymentalerts, time lapse alerts, status reports, fault reporting and/orconfiguration and software updates.

In FIG. 1, an embodiment of a single space parking meter is designatedgenerally by the reference numeral 10. The parking meter 10 includes alocation housing 2, a cash collection box 4, a meter unit 6, and a useridentifier reader 9 such as an RFID reader or a card reader. The cashcollection box 4, the meter unit 6, and the reader 9 are received withinthe housing 2. The housing 2 is fixedly attached to the pole 8. The cashcollection box 4 and meter unit 6 with the reader 9 are removable andreplaceable. The reader 9 receives information from a tag 3 (describedfurther below in connection with FIG. 2) and, for example, can be areader that uses WiFi, Bluetooth, WiMax, or other short range datacommunication technology, in accordance with the configuration of thetag 3.

In some embodiments, for example, where the tag 3 is configured as anRFID and/or a smart card, the tag is powered by the signal transmittedby the reader 9. In other embodiments, the tag 3 can be powered by abattery. Since the operational distance from the reader 9 to the tag 3is relatively small, the power consumed by the reader 9 and/or the tag 3can be very low, such that a relatively small capacity battery that iscompact provides sufficient power to the reader and/or the tag. In someembodiments and deployments, the parking meter 10 can be powered bysolar panels such as photovoltaic structures, which can supplement orreplace battery power. The self-powered feature eliminates the need forwired power connections from an electrical supply utility grid to themeters.

If the tag 3 emits an infrared (IR) beam for data communication, thenthe reader 9 is configured as an IR reader such that the IR beam of thetag is properly received at the reader.

The embodiment of the location housing 2 in FIG. 1 is a clam-shell typeof housing that is affixed to the pole 8 and is configured to mate witha removable meter unit 6. In other embodiments, however, the locationhousing 2 can be a cabinet or other enclosed space that is configured tomate with one or more removable meter units, where the removable meterunits are configured to be mated in compartments or sockets of thecabinet, such that each of the compartments is associated with aphysical location that is not necessarily at the same location as thecabinet or the compartment. In other embodiments, the location housingcan be another type of receptacle fixedly placed and associated with aphysical location.

FIG. 2 shows functional block diagrams of an exemplary removable meterunit 6 and a tag 3 that can be used with meters such as the meter ofFIG. 1. The meter unit 6 includes a radio transceiver 12, an antenna 14,a control module 16, and user interface 18. The radio transceivercomprises a communication subsystem of the meter 10 that includesassociated circuitry and components for communications as describedherein. The control module 16 includes one or more processors such asapplication specific integrated circuits (ASICs), digital signalprocessors (DSPs), digital signal processing devices (DSPDs),programmable logic devices (PLDs), field programmable gate arrays(FPGAs), processors, controllers, micro-controllers, microprocessors,other electronic units designed to perform the functions describedherein, and/or a combination thereof. The control module 16 alsoincludes one or more storage mediums. A storage medium can include oneor more memories for storing data, including read only memory (ROM),random access memory (RAM), magnetic RAM, core memory, magnetic diskstorage mediums, optical storage mediums, flash memory devices and/orother machine readable mediums for storing information. The controlmodule 16 also includes a clock mechanism, which may be provided byappropriate circuitry or alternative constructions, for counting downtime remaining for the current parking session, according to the amountof time paid for by the user.

The user interface 18 provides a means for a location user to interactwith the meter unit 6 and can include, for example, a display, one ormore lights, and a keypad. The user interface 18 can provide a paymentinterface including a currency receiver for receiving coins and/or billsfrom a user in payment for using the parking location, as well as areader for processing credit cards, debit cards, payment tokens, and thelike. The control module 16 is coupled to the user payment interface andis configured to receive payment information regarding the amount of apayment and/or card or token information received at the paymentinterface. The control module 16 communicates the payment informationfrom the user interface 18, via the radio transceiver 12, with themanagement system, or a local data manager of the management system. Theone or more lights of the user interface 18 can be used as an indicatoras to the payment status or, as discussed further below, can be used toproduce an indication that a parking space that is associated with thelocation of the meter 10 is occupied.

The user interface 18 also includes a display 102 and an internal clock104. The display 102 is visible to enforcement personnel, who check forexpiration of the time remaining for the current parking session. Inaddition, the meter unit 6 also includes a short range interface 11 bymeans of which it communicates with the tag 3. The tag 3 has a shortrange interface 13, an ID module 15, and an optional memory module 17for storing identification information regarding the registered user.The meter unit 6 is linked to the tag 3 for data communications by alink 37. The link 37 can be, for example, a radio frequency link or anoptical link. The short range interfaces 11 and 13 can be any type ofnear-field communications (NFC) devices such as, for example, RFIDdevices, Bluetooth devices, WiFi devices, IR devices, smart carddevices, and the like, in accordance with the link 37.

In one embodiment, the control module 16 communicates the identificationinformation, via the link 37, to the short range interface 13 of the tag3. The short range interface 13 can update the optional memory module 17based on the received payment information, such as remaining prepaidbalance or the like. The memory module 17 can deduct the amount ofpayment indicated to have been paid. In addition, the memory module 17can also receive and store transaction-time information including thedate and time of day that the payment was made.

The ID module 15 also stores a unique identifier, e.g., a serial number,that is associated with the tag 3. Preferably, the unique identifier ofthe tag 3 and the value stored in the memory module 17 are externallyreadable via the short range interface 13. The identifier of the tag 3and value stored in the memory module 17 may be read, for example, by asuitable reader of the control module 16. If the short range interface13 is an RFID module, then the reader could be an RFID reader. Othertypes of readers that can be used depend on the configuration of the tagand module, but can include devices such as IR readers, smart cardreaders (contact or non-contact), plug-in readers, and the like. In thisway, reading the identification information stored in the memory module17 and the identifier of the associated tag 3 can be performed in orderto determine the registered user and track payments.

Referring to FIG. 3, a parking meter system that uses a number of theparking meters of FIG. 1 is designated generally by the referencenumeral 20. The system 20 utilizes a number of the parking meters 10. Ingeneral, the system includes one parking meter 10 for each parkingspace. Each of the parking meters 10 communicates with a managementsystem, designated in FIG. 3 by the reference 26. The parking meters canbe operated according to groups, such that a predetermined number ofparking meters 10 comprise group members and each group includes a localdata manager 22. Thus, each group of parking meters 10 and itsassociated local data manager 22 can form a local group 24. In FIG. 3,each operational group is indicated by a dashed line. In one embodiment,there are approximately thirty parking meters 10 in each local group 24.For simplicity of illustration, not all the parking meters 10 are shownin the local groups 24 illustrated in FIG. 3.

Each of the parking meters 10 communicates with the management system26. They may also additionally communicate with their respective localdata manager 22. In the example system 20 this is effected by means of acellular telephone network, with each local data manager 22 and themanagement system 26 being connected to a respective base station 28 ofthe cellular telephone network. Data links are thereby establishedbetween the local data managers 22 and the management system 26.Similarly, communication can be established between the parking meters10 and the management system 26. The management system 26 can performmanagement tasks associated with maintaining the local data managers 22in proper operational condition and managing operations of the system.In FIG. 3, the management system 26 is generally indicated by dashedlines. Although only three local groups 24 are shown in FIG. 3, itshould be understood that there can be more or fewer of the local groups24.

Each local data manager 22 has a modem 30, a control device 32, a memory34, and a radio transceiver 36 with an antenna 38. As indicated above,each local data manager 22 communicates with the parking meters 10 inits local group 60 via its radio transceiver 36 and the radiotransceiver 12 of the parking meter 10. The local data managers 22 maydo so directly, or indirectly via another parking meter 10 as indicatedwith parking meters 10-4 and 10-5 in FIG. 3.

The memory 34 of a data manager 22 can include one or more memories forstoring data, including read only memory (ROM), random access memory(RAM), magnetic RAM, core memory, magnetic disk storage mediums, opticalstorage mediums, flash memory devices and/or other machine readablemediums for storing information. The memory 34 stores the paymentcollection history information received from the parking meters 10 inthe local group 60. The payment collection history information stored inthe memory 34 is communicated to the management system 26 via the modem30, the base station 28 and any intervening networks such as, forexample, the Internet.

The control device 32 comprises one or more processors coupled to thememory 34 and configured to control the functions associated with theradio transceiver 36 and the modem 30. The processor can include one ormore of application specific integrated circuits (ASICs), digital signalprocessors (DSPs), digital signal processing devices (DSPDs),programmable logic devices (PLDs), field programmable gate arrays(FPGAs), processors, controllers, micro-controllers, microprocessors,other electronic units designed to perform the functions describedherein, and/or a combination thereof.

Alternatively to communicating with a local data manager 22, someembodiments can provide the parking meter 10 with a radio transceiver12, shown in FIG. 2, that communicates with the management system 26rather than through a local data manager 22. In these embodiments, theradio transceiver 12 can comprise a cellular telephone transceiver, aMAN transceiver, a satellite transceiver, or other type of transceiverthat communicates over a network to the management system 26 withoutusing an intermediary (local) data manager.

The management system 26 communicates with the parking meters 10 andoptional local data managers 22 and includes a controller 40 with amodem and a database store 42. It also has a communication module forcommunicating with financial institutions (not shown) to obtainauthorization for credit or debit card payments and payment. The modemof the management system 26 can be any modem configured to communicateover a network such as 3G networks or the Internet. In one embodiment,the data store 42 includes a database that stores tag IDs and/or parkingsensor IDs and associates the IDs with the unique physical locations andthe removable meter unit IDs in order to store the payment collectionhistories.

In a typical implementation, the transceivers 12 of the removable meterunits 6 and the transceivers 36 of the local data mangers 22 have apower rating of about 1 mW and have a useful range of about 80 meters.Thus, each local group 24 can extend over an area having a radius ofapproximately 80 meters. Such a configuration is easily achievable withcurrently available technology. Alternative configurations may besuitable with other operating ranges and technologies.

In use, if a person wishing to park at a space associated with a parkingmeter as described herein wants to pay for parking time by means of atag comprising a credit card or debit card or other payment token, therelevant information is read by a reader of the parking meter and istransmitted to the management system 26, directly over the celltelephone network or via the relevant local data manager 22. Themanagement system 26 obtains authorization and communicates theauthorization back to the appropriate parking meter 10 directly or viathe relevant local data manager 22. Status reports, fault reporting,and/or configuration and software updates, may be communicated betweenthe parking meters 10, the local data manager 22, and/or the managementsystem 26.

In one embodiment where the parking meter 10-4 can communicate with oneor more other intermediate parking meters 10-5, and the intermediateparking meter 10-5 in turn can communicate with the local data manger22, the parking meters 10-4 and 10-5 can communicate using a meshnetwork protocol. Mesh network protocols can be provided by severalconventional protocols including Bluetooth, WiFi, and 802-15 (e.g.,802.15.4 commonly referred to as WPAN (Wireless Personal Area Network)including Dust, ArchRock, and ZigBee).

Referring to FIG. 4, an example of a local group 24-1 of parking meters10 that can be monitored by the parking meter system 20 of FIG. 3 isshown. The local group 24-1 includes eight parking meters 10, but othernumbers of parking meters 10 could be included in the local group 24-1.Each parking meter 10 is fixedly located at and associated with aparking space 50. The parking spaces 50 are angled parking spaces thatcould be located in a parking lot or on a street, for example. Otherarrangements of parking spaces are suitable, such as parallel spaces,and will occur to those skilled in the art.

The parking meters 10 each include a removable meter unit 6, such as theremovable meter units 6-1 and 6-2 illustrated in FIGS. 2A and 2B, thatinclude a radio transceiver 12. The eight parking meters 10 communicate,via the radio transceiver 12, with the antenna 38 and the radiotransceiver 36 of the local data manager 22. The parking meters 10 cancommunicate directly with the local data manager 22, as illustrated byconnections 62, or indirectly (e.g., using a mesh network) via one ofthe other parking meters 10, as illustrated by connection 64 betweenparking meters 10-4 and 10-5. As discussed above, the removable meterunits communicate information to the local data manager 22, theinformation including tag IDs, parking sensor IDs, removable meter unitIDs, payment collection information including currency received andcredit/debit card information.

Each of the parking spaces 50 has an associated parking sensor thatdetects when a vehicle is parked in the parking space 50. Each of theparking spaces 50 in the local group 24-1 is shown with three parkingsensors 51, 52, and 53. Typically, a single parking space 50 only hasone parking sensor, it should be understood that the example shown inFIG. 4 shows three possible locations for purposes of illustration.

The parking sensors 51, 52, and 53 can be any of various sensors todetect occupancy (and vacating) of the physical location associated withthe space 50, including magnetic field sensors, motion sensors, contactsensors, and the like. The parking sensors 51 and 52 are located awayfrom the parking meters 10 whereas a sensor such as the parking sensor53 is co-located with one of the parking meters 10. Preferably, each ofthe remote parking sensors 51 and 52 includes a short range wirelessinterface that is configured to communicate with the short rangeinterface 11 of the parking meters 10, as illustrated by the connections54 and 56 in FIG. 4. Alternatively, the remote parking sensors 51 and 52could be connected via a wire to one of the parking meters 10. Theco-located parking sensors 53 could be connected via a wired or wirelessconnection to the parking meter 10 with which each is co-located (e.g.,using similar connections as the tag connection 37 discussed above).

The parking sensor 51 could be, for example a magnetic field sensor thatis affected by the presence of a large metallic object such as avehicle. The parking sensor 51 could also be a motion sensor that istriggered by motion of a vehicle or a contact sensor (including sensorssuch as an accelerometer or inclinometer) that is triggered by theweight of a vehicle. The location of the parking sensor 51 as depictedin FIG. 4 is only an example. Those skilled in the art will understandthat other locations could also be suitable. The parking sensors 51 aresufficiently sensitive to detect a vehicle that is present in theparking space 50 with which the particular parking sensor 51 is uniquelyassociated, but are not so sensitive that they produce a “falsepositive” signal, such as if they mistakenly determine that a vehicle ina neighboring parking space is parked in the parking space 50 that isuniquely associated with the particular parking sensor 51 and parkingmeter 10.

The parking sensors 52 are located at the base of each parking meter 10.For example, a sensor 52 could be located at the bottom of the supportpole 8 for a meter (see FIG. 1). This location has the advantage ofbeing close to the parking meter 10, thereby affording a shorttransmission distance and low power consumption for communications. Inaddition, with a base location, the parking sensor 52 will not beblocked by the presence of a vehicle in the associated parking space, aswould be the case if the parking sensor 51 were located in the middle ofthe parking space 50. The parking sensors 52 detect the presence of avehicle in the associated space and can be sensors such as magneticsensors, motion sensors, or contact sensors.

The co-located sensors 53 could also be magnetic sensors, motionsensors, or contact sensors. In the case of contact sensors, the parkingsensor 53 could simply be a button that a person manually interactswith, thereby alerting the meter 10 that the associated parking space isoccupied.

The remote parking sensors 51 and 52 can be powered by an internalbattery. The typical transmission distances are relatively small, so thebattery lifetime with currently available technology can be on the orderof months or even years. Alternatively, the remote parking sensors 51and 52 could be powered by the meter 10 (e.g., via battery or solar cellcontained in the meter 10) if they are connected via a wire. Theco-located parking sensor 53 can be powered by a power source at themeter 10 (e.g., a battery or solar cell).

In some embodiments, the vehicle sensors 51, 52 and 53 can sense anidentifier associated with the vehicle that is parking at a meter 10.The vehicle identifier may be a license plate number that is opticallydetected. The vehicle identifier may be contained in an RFID tag, orother type of tag that can communicate with the sensor using NFC, thatis attached to the vehicle. An RFID tag on the vehicle could beactivated by any one of the sensors 51, 52 or 53 that is located on themeter, on the curb or in the street in the parking space, respectively.The parking sensor 51, 52 or 53 can wirelessly communicate the vehicleidentifier to the meter 10. The vehicle identifier could be stored atthe data manager and linked with a user identifier (e.g., a RFID tagidentification number), the credit/debit card, phone information and/oremail information of the registered user.

Regardless of which type of sensors are used, the parking sensors 51,52, 53 are configured to transmit an indication of an arrival event toone of the meters 10 that is uniquely associated with the parking space50 where the parking sensor is located. In an alternative embodiment,the parking sensors 51, 52, 53 could transmit to any of the parkingmeters 10, as illustrated by the multicast connections 58. In thisembodiment, the local group 24-1 could employ a mesh network protocol.In such a configuration, the parking meters 10 that receive thetransmission from another sensor will forward the arrival eventnotification to the local data manager 22.

Each of the parking sensors 51, 52, 53 has an ID, e.g., a serial number,that is transmitted with the arrival event indication to the parkingmeters 10. The local data manager 22, or alternatively the central datamanager 26, maintains a data base that associates the parking sensor IDswith tag IDs, meter IDs, and location information. This database is usedto keep track of which locations are occupied and to keep track of thecurrency collected and handling credit or debit card transactionsassociated with each location (space).

In the embodiment shown in FIG. 4, the local data manager 22 uses themodem 30 to communicate with the central data manager 26 via theInternet 60. It should be understood that “modem” as used herein refersto any device that provides a communications interface between the localdata manager and the network. The information communicated to thecentral data manager 26 includes tag IDs, removable meter unit IDs,arrival event indication reports, alerts regarding failure to receivepayment subsequent to detecting an arrival event, and payment collectioninformation including currency received and credit/debit cardinformation.

Referring to FIG. 5, another example of a local group 24-2 of parkingmeters 10 that can be monitored by the parking meter system 20 of FIG. 3is shown. The local group 24-2 includes eight parking meters 10, butother numbers of parking meters 10 could be included in the local group24-2. Each parking meter 10 is fixedly located at and associated with aparking space 50 (only four of the eight parking spaces 50 are shown).The parking spaces 50 are parallel parking spaces that can be located ona street, for example.

The parking meters 10 each include a removable meter unit 6, such as theremovable meter units 6-1 and 6-2 illustrated in FIGS. 2A and 2B, thatinclude a radio transceiver 12. The eight parking meters 10 communicate,via the network transceiver 12 with the antenna 38 and the radiotransceiver 36 of the local data manager 22. The parking meters 10 cancommunicate directly with the local data manager 22, as illustrated byconnections 62, or indirectly (e.g., using a mesh network) via one ofthe other parking meters 10, as illustrated by connection 64 betweenparking meters 10-4 and 10-5. As discussed above, the removable meterunits communicate information to the local data manager 22 which thencommunicates the information to the central data manager 26, e.g. viathe modem 30 and the Internet 60. The information communicated to thecentral data manager 26 includes tag IDs, removable meter unit IDs,arrival event indication reports, alerts regarding failure to receivepayment subsequent to detecting an arrival event, and payment collectioninformation including currency received and credit/debit cardinformation.

The location of the parking sensors 51 in the local group 24-2 isillustrated as being in the street at the edge of the respective parkingspaces 50. This sensor location ensures that the sensor transmissionsignals will not be blocked by a vehicle parked in the parking space 50.In one embodiment, the parking sensors 51-53 transmit to any of theparking meters 10 utilizing a mesh network protocol, as illustrated bythe connections 58.

In one embodiment, the parking sensors 51, 52, 53 use shielding in orderto detect an arrival event when a vehicle enters the associated parkingspace 50 and to avoid a false arrival event detection, e.g. due tovehicle traffic in the street or parking lot where the parking space 50is located. The shielding can include physical shielding that preventsdetection in one or more directions. For example, the parking sensors 51in FIG. 5 could be shielded from detecting vehicles in the street. Theshielding can also be implemented in software where signals emanatingfrom one or more directions are not considered indicative of an arrivalevent.

Referring to FIG. 6, a flowchart of an embodiment of a process 2000 foroperating a meter in the parking meter system 20 of FIG. 3 isillustrated. The process 2000 illustrates an embodiment for makingremote payments associated with a parking meter such as the parkingmeters of FIG. 1, including remotely adding time to the parking meterprior to expiration of time at the meter. The embodiment of the process2000 uses an RFID tag as the user identifier, but other embodimentscould user other forms of user identifier such as a credit card, a debitcard, a smart card (contact or contactless), or a driver's license, forexample.

The time addition process 2000 starts at block 2002 where a user of thepay-by-cell service registers with the management system 26 of theparking meter system 20. The registration can be conducted over theInternet, in person, over a telecommunication system, or by any othermethod that can provide the user registration information. Atregistration, the user provides credit/debit card information for acredit/debit card that will be used to make the pay-by-cell payments.Optionally, the user could also provide bank account information. Theuser also provides cell phone information (e.g., handheld or in-vehicle)with which the user can be contacted regarding future pay-by-cellnotifications.

In one embodiment, the user is provided with an RFID tag that can beused to communicate with a parking meter 10. In this embodiment, an RFIDtag identification number is also linked to the credit/debit card, phoneinformation and/or email information of the registered user. This tagidentification number creates an association between the credit card,the RFID tag, the cell phone number and/or the email address of theregistered user. The RFID tag can be carried about by the registereduser and can be placed on a key chain, in a wallet, or affixed to theback of a cell phone, for example.

After registering with the management system 26, the user, at block2004, initiates a payment session with a parking meter where the user isparking a car at a designated location associated with the parkingmeter. The user can initiate the session by pushing a button on the userinterface 18 of the parking meter. Pushing the button wakes up thecontrol module 16 (FIG. 2) of the parking meter 10. Alternatively topushing a button, the user could initiate reading of a smart card, acredit/debit card, an RFID tag, a driver's license or other useridentifier by inserting one of the cards into a card reader or placingthe RFID tag or contactless smart card in proximity to a respectivereader of the parking meter.

In one embodiment, initiating the payment session at block 2004 includesa parking sensor (e.g., one of the parking sensors 51, 52 or 53 shown inFIGS. 4 and 5) sensing an identifier associated with a vehicle that isparking at a parking meter. The vehicle identifier may be provided in avariety of mechanisms, such as a license plate number that is opticallydetected by the sensor. The vehicle identifier may be contained in anRFID tag that is attached to the vehicle. An RFID tag on the vehiclecould be activated by a parking sensor that is located in proximity tothe parking space. The parking sensor can wirelessly communicate thevehicle identifier to the parking meter. The vehicle identifier could bestored at the data manager and linked with a user identifier (e.g., aRFID tag identification number), the credit/debit card, phoneinformation and/or email information of the registered user.

Upon initiation of the payment session at the block 2004, the process2000 continues to block 2006, where payment information is communicatedto the management system 26. In one embodiment, the user uses a cellularphone to communicate the payment information (e.g., user identificationand/or an amount of time to be purchased) and to communicate the meteridentification information to the management system 26. In oneembodiment, the management system 26 can use a caller ID feature of thecellular telephone network to identify the registered user and toidentify the associated credit/debit card information of the user.

In another embodiment, the user swipes the RFID tag 3 provided followingthe registration in the proximity of an RFID reader associated with theparking meter, such as a reader integrated with the control module 16.The swipe wakes up the parking meter, which then contacts the managementsystem 26, via the radio transceiver 12, with the RFID tagidentification number and with the amount of time being paid for (thiscould be entered by the user using the user interface 18). Themanagement system 26 then uses the RFID tag identification number toidentify the associated credit/debit card information of the user andconfirm payment to the meter.

Upon receiving the payment information at block 2006, the managementsystem 26 processes the payment transaction. Upon successful completionof the payment transaction, the process 2000 continues to block 2008where the management system 26 wirelessly communicates informationconfirming the successful payment of the amount of time requested by theuser to the parking meter. At block 2010, the control module 16 of theparking meter causes the purchased time to be displayed on the display102 of the user interface 18. At this point, the parking meter goes intoa low power mode. The low power mode can shut off power to all systemsof the parking meter except the internal clock and the meter display.For example, all communication circuitry of the meter can be turned off.In addition, the control module 16 can periodically monitor the paidtime remaining. The meter display is visible to parking enforcementpersonnel.

At block 2012, the control module 16 wakes up when the internal clockindicates that the paid parking time remaining falls below a thresholdlevel. For example, if the time remaining falls below 5 minutes, theclock could signal the control module to wake up. Upon waking up, thecontrol module 16 contacts the management system 26, using the radiotransceiver 12. The central data manager then contacts the user, atblock 2014, via a text message to the cell phone of the user. In oneembodiment, the parking meter contacts the user directly at block 2012via a text message, for example, and in that case the block 2014 can beomitted. In order to contact the user directly, at block 2012, the phonenumber of the user could have been communicated to the parking meter bythe management system 26.

The text message sent to the user informs the user that the time isabout to expire and provides a phone number or email address where themanagement system 26 can be contacted. If the user wishes to add time tothe meter, the user contacts the management system 26 at block 2016. Theuser can contact the central data manager by email, text message orphone call. If the user chooses not to add time, the clock at theparking meter will expire and the parking meter can display a violationindication. The parking meter can contact the management system 26 justprior to expiration to see if additional time has been purchased.

If the user chooses to pay for additional time to park at the parkingmeter, the process 2000 continues to block 2018, where the managementsystem, upon receiving the user's request for additional time, processesanother payment transaction. In one embodiment, the credit card couldhave been used to pay for pre-paid parking time, thereby creating anaccount of minutes associated with the registered user, and minutescould be deducted from the user's account. Upon successful completion ofthe payment transaction, the management system 26 communicatesinformation indicating the additionally purchased time to the radiotransceiver 12 of the parking meter. In some embodiments, uponsuccessful completion of the payment transaction, the management system26 communicates an electronic receipt to the cell phone of the userand/or to an email account of the user. The management system 26 couldalternatively communicate the receipt to a Web site that the user canuse to retrieve the receipt at a later date.

At block 2020, the radio transceiver 12 of the parking meter receivesthe additional time information and adds the additional time to the timeremaining, if the meter has not expired already, to determine an updatedtime remaining. The updated time remaining is then displayed on thedisplay 102 of the user interface 18. The parking meter then returns tothe low power mode, such as a sleep mode, and the process 2000 continuesback to the block 2012, where the control module 16 periodically checksthe time remaining and will again wake up the communication circuitrywhen the time remaining for the parking session falls below thethreshold level.

The process 2000 is exemplary and it should be understood that blockscan be omitted, rearranged and/or new blocks added. For example, themanagement system 26 could contact the user at block 2014 prior toreceiving a message from the parking meter at block 2012. In thisexample, the actions at block 2012 could be omitted since the managementsystem 26 contacts the user without notification from the parking meter.

Referring to FIG. 7, a flowchart of an embodiment of a process 2100 foruser-initiated remote payment of a meter such as the parking meter ofFIG. 1 in the system of FIG. 3 includes the stages shown. The process2100 enables a user to add additional time when the user knows that timewill expire before the user can get back to the parking space andreplenish the meter time. Stages 2102, 2104, 2106, 2108, and 2110 arethe same as the stages 2002, 2004, 2006, 2008, and 2010, respectively,discussed above in reference to the process 2000 of FIG. 6. In theprocess 2100, entering a low power mode at stage 2110 is optional suchthat the parking meter can be either fully powered or in a low powermode. In the low power mode, the radio transceiver 12 is powered suchthat it can detect an incoming call and restore full operation of themeter.

At stage 2112, the registered user contacts the management system 26using the cell phone that the user registered at stage 2102. Themanagement system 26 can identify the cell phone of the user which willthen identify the user and the parking meter that the user paid for atstage 2104. The user then remotely pays for additional time using voicecommands or key presses on the cell phone.

Subsequent to the user remotely paying for additional time, the process2100 continues at stage 2114 where the management system 26, uponreceiving the user's request for additional time, processes anotherpayment transaction. In one embodiment, the credit card could have beenused to pay for pre-paid parking time, thereby creating an account ofminutes associated with the registered user, and minutes could bededucted from the user's account. Upon successful completion of thepayment transaction, the management system 26 initiates a communicationsession with the parking meter and communicates information indicatingthe additionally purchased time to the radio transceiver 12 of theparking meter.

At block 2116, the radio transceiver 12 of the parking meter receivesthe additional time information and adds the additional time to the timeremaining, if the meter has not expired already, to determine an updatedtime remaining. The updated time remaining is then displayed on thedisplay 102 of the user interface 18. The parking meter then optionallyreturns to the low power mode and the process 2100 continues back to theblock 2112.

The process 2100 is exemplary and it should be understood that blockscan be omitted, rearranged and/or new blocks added.
